Abstract

1,180,136. Cross-bar switches. INTERNATIONAL STANDARD ELECTRIC CORP. 30 Nov., 1967 [2 Dec., 1966], No. 54592/67. Heading H1L. A cross-bar switch selecting finger comprises a helically wound coil of metal wire whose adjacent turns touch each other and are mechanically prestressed so as to rapidly damp vibration arising from movement of the finger. The finger may be attached, as by a plastics sleeve, crimping &c., to a C-shaped clip which is then pushed on to a selecting bar of circular section (Figs. 1-10 and 15, not shown) or it may be attached as a forced fit in an aperture (bushed or unbushed) in the bar which may be of circular or U-shaped section (Figs. 11-14, not shown) or, as shown, it may be screwed-on to a bolt projecting from the bar.
